DNA repair, the collection of highly-regulated mechanisms by which a cell identifies and repairs DNA damage, remains one of the most essential processes of human life. Without DNA repair mechanisms cells lose the ability to transcribe important regions of their genome, resulting in harmful mutations, which could eventually jeopardize cellular wellbeing. Sources of DNA damage include double-stranded breaks and DNA intra- and interstrand crosslinks, which can ultimately become malignant tumours, leading to cancer. To study DNA repair, single-molecule studies have proven to greatly enhance understanding at the molecular level. However, it is often challenging to obtain adequate sensitivity and resolution, as well as biological conditions mimicking in vivo environments.

 

This DNA Repair Visualization Application Note explains how LUMICKS’ C-Trap™ allows for real-time visualization of the interaction between DNA and DNA repair proteins, under biologically relevant conditions with high spatial and temporal resolution.
